joystick_update ? query joysticks for status changes |
#include <vgajoystick.h> int joystick_update(void); |
queries all currently opened joysticks for position changes and calls the appropriate event handlers. A non-zero value is returned if and only if any joystick reported a position change. In more detail the logical and of the return value and (1 << joydev) is non-zero if this joystick status changed. |
This function is only available in ELF versions of svgalib. Due to backwards compatibility issues it cannot be used with shared a.out libs. |

The svgalib joystick handler was mostly done by Daniel Engstr\"om <daniel.engstrom@riksnett.no>. Multiple joystick, VC switching support and code to glue it into svgalib by Michael Weller <eowmob@exp-math.uni-essen.de>. Part of the code is based on code from C. Smith and Vojtech Pavlik. |
